The problem is the size of root.star. There is a 2 GiB limit for files in a ISO9660 filesystem (and the workaround reportedly does not work in general). Probably star's tsize option is needed, to split the backup into 1 or 2 GiB "tapes". -- ____________________________________________________________________ TonyN.:' The Great Writ <mailto:tonynelson@xxxxxxxxxxxxxxxxx> ' is no more. <http://www.georgeanelson.com/>
